On each page, you’ll see an EditonGitHub button in the top right. Click this to go to the source file in the Great Expectations GitHub repo.

1B. Edit from Github

If you’re already on GitHub, the docs are located in great_expectations>docs. You can directly navigate to the respective page you want to edit (but getting there from docs.great_expectations.io is a little easier).

In the top right of the grey header bar of the actual file, click the pencil icon to get into edit mode on GitHub.
